.Specification of Letters Patent.

Patented Aug. 2'7, 1918.

Application filed June 14, 1917. Serial No. 174,808.

The invention relates to the manufacture and application to laces and the like of metallic tips; and has particular reference to tapered tips. Heretofore it has been the practice to manufacture tapered tips indi vidually and apply them individually thus making the operation of application comparatively slow.

The object of my invention is to overcome this disadvantage and enable a plurality of tapered tips to be applied simultaneously.

My invention may be said to consist of a ribbon of blanks of peculiar configuration in that it has a longitudinal series of diamond shaped openings arranged transversely to its length and with their opposite points a short distance inward from the margins of the ribbon. Another feature of the invention consists of the tip per 86 which has as distinctive features a, cylindrical base and a circumferential series of inward friction points the main portion of the tip being of prolate truncated conical form.

For full comprehension, however, of my invention, reference must be had to the accompanying drawings in which similar reference characters indicate the same parts and wherein:

Figure l-is a plan View of my improved ribbon of blanks;

Fig. 2 is a fragmentary View of the blank drawn to a larger scale;

Fig. 3 is a sectional view of the blank taken on line 33 Fig. 2; and

Fig. 4 is an elevation of a pair of tapered tips as they are simultaneously produced from the blank.

In order to obtain a clear description of this invention and the manner in which it is applied, reference may be had to my companion application for patent Serial Number 224,693, filed on the 25th day of March, 1917,

in which a machine is illustrated specially designed to convert the ribbon into the tips and apply. the tips to laces.

The ribbon of blanks is indicated at b. It is of thin sheet-metal and of a width equal to the aggregate length of two tips. A series of diamond-shaped openings 0 extend transversely to the length of the ribbon with their opposite points a short distance inward from the margins to leave side or marginal portions d by which the blanks are united. These marginal portions cl are per: forated as at c in a manner to strike up points 7. The ribbon is divided into blanks as shown in Fig. 2 and each of these blanks is adapted to be Wrapped around a lace as shown in Fig. 4:, thus forming a pair of tapered tips with their apices united and the points f engaging the lace and thereby causing the tips to firmly adhere to it. In the finishing operation the tips are separated.

This particular construction or ribbon enables it to be automatically fed and cut off and the machine referred to eliminates the surplus metal in the forming of the tapered tips.

What I claim is as follows 1. A tip for a lace for shoes and the like consisting of prolate truncated conical form having a cylindrical base portion the diamterof which is uniform throughout and less than the width of the lace, said base portion being provided with a circumferential series of inward friction points for causing the tips to adhere to the laces.

2. A metal ribbon of blanks of tapered tips for lacing material such metal ribbon having straight side edges and a longitudinal series of diamond-shaped openings each extending transversely to the length of the ribbon and with their opposite points a short distance from the margins of the ribbon to constitute a cylindrical base portion.

3. A metal ribbon of blanks of tapered tips for lacing material such metal ribbon having straight side edges and a longitudinal series of diamond shaped openings each In testimony whereof I have signed my name to this specification in the presence of two Witnesses.
